Answer 5: Hmmmm. I don't know what kind of fancy aluminum foil you've been using, Nicole, but aluminum foil gets really hot in my oven. To understand why this happens, it's good to know what "temperature" and "heat" really mean. Everything is made of molecules and atoms, and all atoms are made of a very heavy nucleus with a bunch of small electrons orbiting around it like moons. The temperature of an object tells you how fast the molecules in that object are moving. When something gets really hot, its molecules get moving around really fast. When you heat up a liquid (like water), the liquid molecules start moving so fast that they stop sticking together, and they change from a liquid into a gas (this is what happens when water boils). The same thing happens when you heat up a solid (like

 why do people think blondes are stupid

why do people think blondes are stupid

Why are we told blondes are dumb? Or have more fun? Or are preferred, as Anita Loos once said, by gentlemen? Why, indeed, are people generally barraged with stereotypes about body shape, form or looks? Or attributed behaviours that are supposed to follow a particular physical characteristic?

Often as prelude to the targets being convinced to buy some product that will fix or produce the look. It leverages from a raft of factors, including pressure to conform and anxieties over self-image, and is why men spent up large on wigs and women accepted being crushed in corsets, way back when.

Different vitamins have different roles in the body, but all the vitamins are vital for healthy growth and development before birth and throughout life.
